11.2.10.5 Change Notification — If ExecChgCtrl requires that the originating namespace be notified of changes,
the notification service RMEChange is sent to the specified namespace indicating the type of change that has
occurred.
Figure 11.3
RMEChange Message Flow
The recipe executor may or may not have direct communication links with the namespace itself. However, in this
case, the necessary links may be assumed to exist with the supervisor or other owner of the recipe executor, or it
would not be possible for recipes to be downloaded in the first place.
The originating namespace, on receipt of a change notification, is responsible for uploading the changed recipe and
for synchronizing through the service RMERename any change in identifier that might result from changing a write-
protected recipe.
11.3 Table of Operations — Table 11.1 lists all the operations defined for recipes and namespaces.
The column labeled "Rqmt" indicates those operations that are required for fundamental compliance to the RMS
recipe execution resource.
Table 11.1 Recipe Executor Operations
Operation Description Rqmt
Recipe download and verify Transfer execution recipe to local storage. If the recipe is unverified, then verify it
at this time.
Y
Recipe verify Verify a stored execution recipe. Y
Recipe unload Transfer a recipe from local storage. Required if the execution process modifies an
executed recipe or if the recipe executor is able to create recipes.
N
Recipe rename Change the recipe’s identifier. Y
Get available storage Calculate the amount of storage available for a single execution recipe, exclusive
of formatting overhead.
Y
Recipe delete Delete a recipe from local storage. Y
Recipe select Select recipes for execution. Y
Recipe deselect Deselect one or more recipes. Y
Get recipe descriptor Get the descriptors of a specified execution recipe. Y
Change notification Inform the originating recipe that a recipe has been originated or changed.
Required if the recipe executor is able to make a change protected by
ExecChgCtrl
or to originate a recipe.

11.4 Recipe Executor Events — The recipe executor shall provide the Recipe Select and Recipe Deselect events.
Recipe executors that are capable of originating a new execution recipe shall provide the New Execution Recipe
event. Recipe executors that are capable of changing the body of an existing recipe shall provide an Execution
Recipe Change Event. These events allow service users other than the originating namespace to receive notification
whenever a new recipe is created or an existing recipe body is modified.
12 Recipe Namespace Services
This section defines recipe management and namespace services (see Table 12.1), which begin with a prefix of
RMN. RMS services used by distributed recipe namespaces and by the recipe executor are defined in later sections.
Recipe management and recipe namespace services request that an operation be performed on a recipe within a
namespace or on a namespace.
Recipe management operations that change recipe attributes are invoked with the RMNAction or RMNVarPar
requests.
Certain activities that require extended time to complete may indicate the intent to comply in the response message
and then provide confirmation with the RMNComplete message at the completion of each individual operation
specified.

12.1 Recipe Management Message Parameter
Dictionary — Table 12.2 contains the definitions for
message parameters, and their components, used by
namespace services.
For purposes of transferring a recipe with its
components, it is regarded as having three types of
sections: a section containing the generic attributes, a
section consisting of the body, and a section containing
the attributes of the agent-specific dataset. The generic
section is always transferred first, and the attributes
AttrLength
, AttrTimestamp, BodyLength, and
EditTime
are always sent first, in that order. This
allows the length information to be immediately
determined by the receiver. Agent-specific dataset
sections are sent last, since the number of agent-specific
datasets will vary.
Descriptors are also regarded as consisting of sections
for the generic descriptor, the body descriptor, and zero
or more agent-specific descriptors.
Each start of each section is identified with a text string
reserved for that section type.
